Abstract:
The invention relates to an electric cable (16) having an inner conductor (16a), a primary isolation (16b) surrounding the inner conductor, an electrical shielding (18) surrounding the primary isolation (16b), and a secondary isolation (16c) surrounding the shielding, wherein at least on one end (22) of the cable (16) the secondary isolation (16c) is removed, such that the shielding (18) is stripped. A contact of the shielding with a vehicle body is electrically and mechanically ensured in that a sleeve (2) is pushed over the stripped shielding (18), a part of the shielding (18) protruding over the sleeve (2) is put over the sleeve (2), and the part of the shielding (18) that is put over the sleeve (2) is connected to the sleeve (2) in such a manner that an intermetallic compound is formed.
Abstract:

The sealing assembly comprises a metal ring (1) having a mounting hole therein; a ceramic ring (2) having a connecting hole therein and disposed in the mounting hole; and a core column (3) disposed in the connecting hole, wherein at least one of an inner circumferential wall surface of the metal ring, an outer circumferential wall surface of the ceramic ring, an inner circumferential wall surface of the ceramic ring and an outer circumferential wall surface of the core column is configured as an inclined surface, and an inclination angle of the inclined surface relative to a vertical plane is about 1 degree to about 45 degrees.
Abstract:
Die Erfindung betrifft eine Vorrichtung zum Verschweissen von Schweissgut in einem Verdichtungsraum (2) mittels Ultraschall, wobei der Verdichtungsraum (2) in einer Schweissposition von Abschnitten von aneinander angrenzenden Begrenzungsflächen (4, 6, 8, 17) umschlossen ist. Die Begrenzungsflächen umfassen eine Schweissfläche (4), welche an einer Ultraschallschwingungen übertragenden Sonotrode (3) ausgebildet ist, eine Ambossfläche (17), welche an einem Amboss (16) ausgebildet ist und in der Schweissposition als Gegenfläche gegenüber der Schweissfläche (4) angeordnet ist, eine Seitenfläche (8), welche an einem seitlichen Begrenzungselement (7) ausgebildet ist, eine Schieberfläche (6), welche an einem Schieberelement (5) ausgebildet ist und gegenüber der Seitenfläche (8) angeordnet ist. Dabei ist wenigstens eine der Begrenzungsflächen (6) derart beweglich ausgebildet, dass eine Ausrichtung relativ zur gegenüberliegenden Begrenzungsfläche (8). Die Erfindung betrifft auch ein zugehöriges Verfahren zum Verschweissen von Schweissgut mittels Ultraschall.
Abstract:
A method of welding two workpieces together is described. A conductor in electrical communication with a pulse circuit is provided. A portion of the second workpiece is located adjacent the conductor. The two workpieces are also located together. A portion, or all, of one workpiece is welded to the other by applying a pulse current to one of the workpieces. A method of forming a workpiece is disclosed using a pulse current to move the workpiece into a desired shape.
Abstract:
A coaxial connector for interconnection with a coaxial cable with a solid outer conductor by laser welding is provided with a monolithic connector body with a bore. A sidewall of the bore is provided with an inward annular projection angled toward a cable end of the bore. A sidewall of the inward annular projection and the sidewall of the bore form an annular laser groove open to a cable end of the bore. The annular laser groove is dimensioned with a taper at a connector end of the laser groove less than a thickness of a leading end of the outer conductor. The taper provides an annular material chamber between the leading end of the outer conductor, when seated in the laser groove, and the connector end of the laser groove.
Abstract:
A solder pre-form for soldering a coaxial cable to a connector body is provided with a plurality of flux grooves on a cable side and a connector side. The solder pre-form may also have a plurality of holes between the cable and connector sides. In a method of use, flux is applied to the flux grooves and the solder pre-form applied to encircle the outer conductor which is then inserted into the connector body and the solder pre-form melted to complete the solder interconnection. Where holes are present, flux may be applied to the connector side, passing through the holes also to the cable side.
Abstract:
The invention relates to a method for connecting soldered connection-conductors (3) that consist of aluminium or an aluminium alloy, having a 0.2% yield point of less than 120 N/mm2, to photovoltaic solar cells (7, 7a, 7b, 7c) that have metallisations on the upper and lower sides, by means of a soldering method such as IR soldering, inductive soldering, thermal-contact soldering, ultrasound soldering, or hot-air soldering. The solar cell metallisations can be pre-soldered. An additional solder material (2a, 2b) can be arranged between the connection-conductors (3) and the metallisation of the solar cell (7, 7a, 7b 7c). This procedure allows the solar cells (7, 7a, 7b, 7c) to be connected together in series.
